Each trial included the choice of four types of barley seeds [1.6 (control), 4.8, 7.1, and 16.8 mg sodium/g seed]. Seed use by deer mice and white-footed mice differed with sodium concentration but was not affected by locality (eastern versus central Kansas) or gender. In contrast, seed use by cotton rats was not influenced by sodium content and, although seed use differed between males and females (females tested were larger than the males), relative use of seed types was not affected by gender. Average sodium concentration of seeds used did not differ with locality or gender for either deer mice or white-footed mice, or among deer mice (6.6 mg/g), white-footed mice (5.6 mg/g), and cotton rats (6.2 mg/g).1 aRustiati, E.L.1 aKaufman, D.W. uhttp://lter.konza.ksu.edu/content/effect-sodium-seed-choice-deer-mice-white-footed-mice-and-hispid-cotton-rats
